The GC/Koni setup is a nice one. The top hats are nice cause they extend shock travel so you can get a little lower without riding bumpstops all the way. Don't get the pillow ball mounts, they'll make the ride harsher and increase road noise, for very little gain.

If you want to mount sway bars, get the LCA's, they'll make a big difference (the swaybars that is). Just don't get the LCA's by themselves thinking it's going to be a night and day difference, cause it won't. If you want bling, definately get them, kinda neat to see the anodized parts underneath the car when you see it from behind. If you want to mount sway bars cheap, get OEM bars and LCA's off a DC.
